MEUI combines the technicaladvancement of an electronic controlsystem with the simplicity of directmechanically controlled unit fuelinjection. The MEUI system excels inits ability to control injection pressureover the entire engine operating speedrange. These features allow the C32 tohave complete control over injectiontiming, duration, and pressure.

ATAAC and Airflow. Air-to-airaftercooling keeps air intaketemperatures down and, in concert withthe tight tolerance combustion chambercomponents, maximizes fuel efficiencyand minimizes emissions. Significantimprovements in air flow are generatedby water-cooled turbochargers, uniquecross-flow head, single rear-drivenoverhead cams, and a more efficientintake manifold.

Engine maintenance and repair.Is easier through monitoring keyfunctions and logging critical indicators.Electronic diagnostic access is possiblewith the Electronic Technician (Cat ET).

Aluminum Spacer. Located betweenthe block and head to eliminate theneed for block counterbores, andextend block life.

Hardened-faced valves. Through-hardened crankshaft journals and steel-backed, copper-bonded aluminumbearings, help assure reliable performancein the toughest duty.

Components have longer life. Becauseoil-cooled pistons and full-length, water-cooled cylinder liners provide maximumheat transfer. The cylinder heads alsoutilize additional coolant passages toprovide maximum cooling to the engine.

Two-pass cooling system. Using atwo-pass system, the AMOCS radiatorprovides a more efficient heat exchange.The coolant is routed from a sectionedbottom tank up the front side, over thetop of the core, and down the engineside of the core to the bottom tank.This flow pattern allows the coolantto pass through the radiator twicefor better cooling.

Modular Design. The cooling elementsare individual core modules connectedto a sectioned bottom tank. There isno top tank to remove.

• Standard 9.4 steel fins per 2.54 cm(1 in), or an optional 6 steel fins per2.54 cm (1 in)

• Brass tube construction within eachcore for improved reliability

Hydraulically Variable, Demand Fan.The hydraulically driven demand fanprovides engine cooling capability thatis matched to the ambient conditions.In cooler conditions, the fan turns at aslower speed, reducing power demands.This frees up more power in high loadfactor operations or reduces fuelconsumption in lower load factoroperations. Low speed fan operationalso reduces both operator and spectatorsound levels. The ADEM A4 enginecontroller regulates the fan speedthrough a variable displacement pump.An attachment low speed option isavailable for cold weather operationsto avoid over cooling the engine.

Easy Serviceability.

• Servicing of the AMOCS canbe performed without tilting theradiator guard

• No need to remove or replace amajor component as on single-coreradiators

• Each core module can be replacedindividually (without removing theentire radiator), saving considerablecost and repair time

The thumb lever at the top of thehandle, controls blade pitch fore and aft.The trigger switch pitches the bladeforward to dump the load.

The two thumb buttons to the left of theimplement control provide control overthe semi-automated blade pitch functionsthat Dual Tilt provides. Blade pitch forload, carry and spread segments canbe preset on Advisor and controlled bythe buttons. The left side button cyclesbetween the pitch settings for eachsegment of the push cycle. The rightside button cancels out of the pitchfunctions without losing the preset pitchangles. This Auto Blade Assist (ABA)feature is turned on and off using aswitch on the right side console.

Computer Aided Earthmoving System(CAES) (optional). Computer AidedEarthmoving Systems (CAES) replaceconventional surveying with advancedGPS and radio communicationsequipment, improving operator’saccuracy and efficiency. CAES cancommunicate back and forth with theoffice and access site design plans.Office software can generate designs onthe fly and provide customized productionand design reports. CAES gives operatorscontinuous, interactive access to machineand operating information right in thecab – so they have the tools they needto operate with more precision andpredictability. An in-cab display givesoperators easy-to-understand colordiagrams of where to cut and fill.With CAES, the effort of reading mapsor looking for grade stakes is virtuallyeliminated. And because it givesimmediate, accurate feedback, operatorscan doze quickly, accurately andconfidently. CAES helps identify waysto reduce errors and constantly improvethe production process – ultimatelyhelping reduce cost.

AutoCarry (optional). AutoCarry providesautomatic blade control (raise and loweronly) during the carry segment of thedozing cycle. Drawbar pull, groundspeed, track slip, and machine attitudeare integrated to control track slip andmaintain optimal blade loads. AutoCarryis intended to enhance the operator’sproductivity in high productionearthmoving with carry distances over30.5 m (100 ft). By monitoring groundspeed with the belly-mounted radar gun,the auto carry system controls bladeload to maintain approximately 2.4 km/h(1.5 mph) true ground speed. Track slipis monitored and limited to under 16%.Readouts of the true ground speed andtrack slip are available in the AutoCarrymenu on Advisor. Through the system’sDynamic Inclination Sensor (DIS),readouts of the tractor pitch angle andside-to-side scope are also availableon Advisor.

Ripper Control Lever. A rigidly mountedhandgrip provides firm support forthe operator even when ripping in theroughest terrain. The low effort thumblever controls raising and lowering.The finger lever controls shank-in andshank-out positioning. The thumbbutton automatically raises the ripper.
